Interestingly, the bricks-and-mortar Microsoft Stores seem to sell laptops with a version of Win 8 that has no crapware/bloatware and is optimized to run well; a lot like doing a fresh install.
Worth noting that you can also get these at bigger chains (e.g. Costco, Best Buy, etc.) - like the other comment under/above me said, they're labeled as "Microsoft Signature" or something along those lines.
